Background
The Army Geospatial Center (AGC), Environmental Analysis Group (EAG) conducts Geographic Information System (GIS) based Historical Photographic Analysis (HPA) of current, former and closing U.S. military installations and training areas. EAG also analyzes aerial photography and elevation data to address environmental concerns related to land use change, such as historical wetland evaluation, shoreline change, watershed/land use mapping, and produces a variety of baseline environmental analysis. HPA helps our customers address environmental concerns related to previous military and industrial activities. The HPA allows customers to focus restoration and remediation efforts, resulting in significant cost avoidance.
The identification and remediation of hazardous sites is a problem faced by many active, closing, and former U.S. military installations. These problems are complicated by the fact that many of these sites were created by practices and activities undertaken decades ago. These hazardous sites are often completely obscured today due to the burial of materials, rapid revegetation, or dramatic changes in land use. AGC’s Environmental Analysis Group uses historical aerial photography and satellite imagery, both CONUS and OCONUS, to locate potential sites of environmental contamination [e.g. chemical warfare material (CWM), unexploded ordnance (UXO), radioactive material, or landfill locations]. In addition to locating potential contamination sites, the group conducts GIS-based Historical Photogeologic Analyses for areas where groundwater contamination is a concern. For example, locating surface features, such as rock fractures, that can influence the migration of contaminants.
